The influence of electromagnetic waves on the human body. The effect of electromagnetic waves on a person

There are many ways to classify the health effects of electromagnetic radiation.

Here it is necessary to distinguish between biological changes (which are proven by experimental observations at the cellular level) and pathological effects (the generation or aggravation of diseases) proven by epidemiological studies.

The list of health effects of EMR presented here is in fact only a small selection of the large studies currently reported in the scientific literature.

Biological Effects of Electromagnetic Radiation

Here are some of the biological changes induced by electromagnetic radiation from studies (most recent data first):

Protein changes in the skin.

Ten women were asked to volunteer for a study in which they were exposed to EMR (900 millihenries) via GSM cell phones for one hour. After the experiment, the scientists removed their skin cells for examination in order to find any stress responses. They examined 580 different proteins and found two that were significantly affected. (He was increased by 89% while the other was reduced by 32%). Source - New Scientist, February 23, 2008.

Anomalies in the production and quality of sperm.

Researchers at the Cleveland Clinic studied the quality of the sperm of 361 men examined at the fertility clinic. On average, those who spent more hours on cell phones had lower sperm counts and higher rates of abnormal sperm. Source - "New Zealand Herald", February 8, 2008

Irritability of brain cells.

Researchers at the Fatebenefratelli Hospital in Isola Tiberina found that the electromagnetic field emitted by cell phones can cause some cells in the cerebral cortex (adjacent to the side of the head where the phone was used) to become highly aroused for an hour, while others become depressed.

DNA damage.

german research group Verum has studied the effect of radiation on animal and human cells. After the cells were placed in the electromagnetic field of a cell phone, they showed an increase in breaks in their DNA, which could not be repaired in all cases. These lesions can be passed on to future cells, which in turn could become cancerous. Source - "USA Today", December 21, 2004

Damage to brain cells.

A study of the effects of cell phone frequencies (applied at non-thermal intensity) on the rat brain showed damage to neurons (brain cells) in various parts of the brain, including the cortex, hippocampus, and basilar ganglia. Source - Bulletin "Ecomedicine Perspectives", June 2003.

Aggressive growth of leukemic cells.

Researchers at the National Research Council in Bologna, Italy have shown that leukemic cells exposed to cell phone frequencies (900 mH) for 48 hours multiply more actively. Source - "NewScientist" October 24, 2002

Increased blood pressure.

Researchers in Germany concluded that a single use of a cell phone for 35 minutes could cause a 5-10 mm increase in normal blood pressure. Source - The Lancet, June 20, 1998

Adverse effects of electromagnetic radiation.

Here are some of the pathological (disease-causing) effects caused by electromagnetic radiation published in the media (in reverse chronological order):

Salivary gland cancer.

Israeli researchers report that people who use cell phones for 22 hours a month or more are 50 percent more likely to develop salivary gland cancer than those who use cell phones infrequently or never. Source - "Health24", February 19, 2008

Brain Tumor.

An analysis of several previous studies has concluded that cell phone use for more than 10 years causes an increased risk of acquiring certain types of brain tumor (2.4-fold for acoustic neuroma and 2-fold for gliomas). Source - "News24", October 3, 2007

Lymphatic and bone marrow cancer.

Researchers from the University of Tasmania and the University of Bristol studied reports of 850 patients who were diagnosed with cancers of the bone marrow and lymphatic system. They concluded that people who live within 300 meters of a high voltage power line for an extended period (especially during childhood) are 5 times more likely to develop these diseases later in life.

Miscarriage.

Researchers in California have found that EMR from electrical appliances (such as vacuum cleaners, hair dryers, and mixers) can significantly increase a woman's risk of miscarriage. Source - Journal of Epidemiology, January 2002.

Suicide.

American researchers found that the suicide rate among 5,000 electrical workers who were exposed to ultra-low frequencies doubled that of a control group of the same size. The effect was especially pronounced among younger workers. "Journal of Occupational and Environmental Medicine", March 15, 2000

In addition to the above, many other studies have been produced, but not all of them have received media attention.

How does EMI work?

Some scientists previously believed that the only way the radiation could produce harmful effects was if it was of sufficient intensity to produce a heating effect on the tissue. (It was previously reported that talking on a cell phone for half an hour can raise the temperature of the brain in the part of the head where the device came into contact with it).

Subsequently, this theory was strongly condemned by many studies, which proved that the intensity of EMR is not enough for a harmful effect.

The mechanisms by which electromagnetic radiation can trigger disease are not yet fully understood, but experiments are being actively conducted on this issue.

DNA damage.

Our cells have mechanisms to make limited repairs to DNA damage, but EMR appears to interfere with these mechanisms. Damaged DNA is implicated in several diseases at once, including Various types cancer.

Protective antiviral mechanism of the host cell (interference) with the production of Melatonin.

Electromagnetic radiation is introduced into the production of melatonin, a hormone produced in the human body. It has already been proven that low melatonin levels are associated with several diseases, including cancers. (Recent research indicates that serotonin production may also be affected by EMR).

Influence on intercellular communications.

Our somatic cells communicate internally and externally through electrical signals. These signals can be altered by electromagnetic radiation through the production of electrical currents within the body, causing changes in both cellular activity and cellular structures.

Harmful effect electromagnetic radiation health may depend on ...

We don't have all the answers at this stage, but clues from various studies indicate that the health effects of PMF may depend on:

EMP intensity.

Getting into the zone of influence of strong electromagnetic waves can cause harm, even if it is short-lived.

In one study, pregnant volunteers were asked to wear a device that measured the highest intensity (peak) of EMR in a 24-hour period. The results indicated that higher peak EMR levels correlated with higher rates of health damage (miscarriage).

Accumulative effect of EMR.

During the day, a person is exposed to electromagnetic radiation of various frequencies. For example, they can come from electric shavers and hair dryers, from car, bus or train equipment, household items such as heaters, ovens and microwave ovens, neon lights, household wiring, power lines, cell phone wear and use. These are the most common sources.

The combination of these influences can overwhelm the body's defenses and defense mechanisms.

The duration of the EMP.

Numerous studies indicate that damage to health begins to be noticeable only after many years of exposure to EMP, such as from high voltage power lines, or cell phones.

EMF speed.

Greater biological stress from exposure to EMR is experienced by the body from devices with changeable, fluctuating cycles of work (photocopier, printer, etc.) than from constant work.

EMF frequency.

It is still not known for certain what types of electromagnetic waves cause negative health effects, but, apparently, different frequencies cause different negative effects.

Signal overlay.

To produce an analog or digital signal, an electromagnetic wave can be modulated in various ways. Where the wave is used for communications (eg radio, television, mobile telephony, etc.), the signal is superimposed on the carrier frequency. There is evidence that, in some cases, the signal component may be more detrimental than the carrier's EMP.

The medical danger of EMR is real.

The danger to our health caused by high levels of man-made electromagnetic fields is real. To such general conclusion came many of the growing number of responsible scientists and professional workers healthcare systems.

Fortunately, there are many ways to protect ourselves and our loved ones before our health is affected.

The sensitivity of living systems to external electromagnetic oscillations of the biosphere, first of all, depends on the frequency range and intensity of oscillations. Conditionally available for study range electromagnetic phenomena subdivided into three areas, within which there are specific features interactions of electromagnetic fields with biological systems:

low-frequency fields (up to approximately meter wavelengths)
Microwave - meter, decimeter and centimeter waves
EHF - millimeter and submillimeter waves.

Electromagnetic waves carry a certain energy and when they interact with matter, this wave energy is converted into heat.

The latter is also an important condition for the vital activity of various living creatures of the biosphere. At low doses of exposure to electromagnetic waves in the human body, any significant physiological changes not happening. However, electromagnetic waves of any frequency with an irradiation power density exceeding 10 W/cm are harmful to living organisms.

The response of a living system to external electromagnetic influences can occur at various structural levels of a living organism - from the molecular, cellular to the level of the whole organism.

The nature of the interaction of an electromagnetic wave with a living organism is determined both by the characteristics of the radiation itself (frequency or wavelength, phase propagation velocity, oscillation coherence, wave polarization, etc.), and physical properties given biological object as a medium in which the wave propagates. These properties of a substance include dielectric constant, electrical conductivity, wave penetration depth, etc.

Nowadays, the biological effect of electromagnetic waves in the range from constant magnetic fields to visible light (the region of non-ionizing radiation) has begun to be studied very intensively. However, the results of these studies are known only to a narrow circle of specialists, and, as a rule, the rest of the public lives quietly and peacefully according to its own laws. To some extent, this was led to the widespread opinion among the people that since a person does not feel the electromagnetic waves noted above the range, then they do not affect a person at all.

The action of low-frequency electromagnetic waves

For a long time, it was believed that low-frequency electromagnetic fields (EMF), up to the slowly changing magnetic and electric fields of the Earth, do not have any noticeable effect on living organisms. This belief was based on the fact that the biological effects associated with the transformation of the energy of these very weak fields in the tissues of living organisms are negligible. However, in the last decade it has become clear that these low-frequency electromagnetic fields play a significant role in the functioning of wildlife. At the same time, the concept arose that living organisms have evolved to use low-frequency electromagnetic fields to obtain information about changes in the external environment, for information communications between organisms and within living organisms.

In addition, an assumption is also made about the possible influence of fields at ultra-low frequencies, when its frequency is in the infra-low range of 10-3-10 Hz, close to the most important biological rhythms. Indeed, the rhythms of the electrical activity of the brain, heart and other organs are essentially in the same frequency range.

Action of millimeter waves

Why does millimeter wave electromagnetic radiation have a specific effect on living organisms?

The answer to this question is as follows: millimeter radiation of extraterrestrial origin is strongly absorbed by the Earth's atmosphere. Therefore, living organisms could not have natural mechanisms of adaptation to fluctuations of noticeable intensity in this range due to external causes. However, they could adapt to their own similar fluctuations.

In the last 30 years, a purposeful study of the influence of millimeter electromagnetic waves on living organisms has been carried out.

Original studies in this direction have been carried out, and quite interesting and experimental data have been obtained by scientists N. D. Devyatkov, M. B. Golont, N. P. Didenko, V. I. Gaiduk, Yu. P. Kalmykov and others (Russia), Sitko S.P. (Ukraine), Caylman F. and Grundler V. (Germany), Berto A. (France) and others. An analysis of the experimental material accumulated to date allows us to draw two conclusions:

1. Electromagnetic oscillations of low intensity in the millimeter wavelength range have a significant impact on the vital activity of various organisms.

2. Two interrelated effects are found, which differ in the presence or absence of frequency dependences of resonant absorption.

Non-resonance effects are associated with water molecules (H2O) in irradiated organisms, which strongly absorb millimeter radiation. Indeed, water performs extremely important functions in the life of biological objects and the human body.

For example, a flat layer of water only 1 mm thick attenuates radiation at X ~ 8 mm by a factor of 100, and at X ~ 2 mm by a factor of 10,000. Therefore, when human skin is irradiated with millimeter waves, almost all radiation is absorbed in surface layers a few tenths of a millimeter thick, since the weight content of water in the skin is more than 65%. The absorption of millimeter radiation by water molecules in the body is explained by the fact that the frequencies of their rotational movements largely fall in the region of millimeter and submillimeter wavelengths. This absorbed energy is then converted into heat.

In addition, scientists obtained a unique experimental result: when millimeter radiation interacts with biological objects, well-reproducible resonance absorption curves were found. The frequency dependence of this interaction effect is very similar in shape to the resonant characteristic of an oscillatory circuit. For example, the human body can be considered as a good antenna for electromagnetic waves with a frequency of 70-100 MHz; that at these frequencies it "resonates" with the field.

At present, there is no generally accepted point of view explaining the nature of this phenomenon. The question of the mechanisms of the sharply resonant action of millimeter radiation on living organisms is, perhaps, one of the interesting questions in the problem under discussion, which excites the minds of scientists and is the subject of numerous discussions in the scientific literature, at seminars and conferences.

Action of radio waves

At the dawn of the development of radio broadcasting, electromagnetic waves of the radio frequency range for the human body were considered safe. But radio engineering developed, powerful radiation generators appeared, and then scientists discovered that radio waves primarily act on the central nervous system.

The biological effect of radio waves of all ranges is similar, however, with an increase in the frequency of field oscillations, its pathogenic effect increases, reaching the greatest severity in microwave radio waves. In mild cases, due to the so-called non-thermal action, mainly functional disorders occur in the body, which can accumulate with repeated exposure to the microwave field. Irradiation of high intensity gives a thermal effect, leading to persistent changes in the nervous system.

Another case is related to the emission of so-called "radio-wave hearing" - a phenomenon known since 1947. Very often, when microwave impulses act on the head, a person hears "clicks" in time with the impulses; moreover, he has the impression that clicks are heard inside the head. This phenomenon takes place if the power flux density of the pulsed radiation is high enough (about 500 kW/m2).

The action of the visible spectrum of electromagnetic waves

Opening our eyes every morning, we do not think what a miracle it is to see the world around us and its inescapable beauty. Prose can also be added to our computer age: more than 80% of the information entering the "central processing unit" of the human body goes through the main sensory (sensitive) video terminal - the eyes.

The sensitivity of the human eye to light is very high. He is able to perceive and large light fluxes. These fluxes exceed the smallest luminous flux that the eye perceives by trillions of times.

Our organ of vision also allows us to distinguish colors, that is, to perceive radiation differently depending on its spectral composition.

With the same power of the light flux, the yellow-green rays will be perceived by the eye as the brightest, and red and purple will seem the weakest. If the brightness of yellow-green light with a wavelength of X ~ 0.555 µm is taken as unity, then the brightness of blue light of the same power will be 0.2; and the brightness of the red light is 0.1 of the brightness of the yellow-green flux. Even powerful fluxes of radiation with a wavelength shorter than 0.3 microns and longer than 0.9 microns are not perceived by the human eye. The maximum sensitivity of the eye on the wavelength of the light entering it coincides with the maximum emissivity of the Sun.

The great Goethe remarked that yellow awakens bright feelings, blue - causes a feeling of cold, lilac - something bleak, and red - creates a whole range of impressions. Further research by a number of generations of scientists made it possible to use the color spectrum for the treatment and prevention of many diseases. An analysis of these numerous observations and the results of specially designed experiments leads to the following conclusions:

Red color stimulates the nerve centers, left hemisphere, energizes the liver and muscles. However, prolonged exposure can cause fatigue and increased heart rate. Red color is contraindicated in case of fever, nervous excitement, hypertension, inflammatory processes, neuritis, it also has a bad effect on bright red-haired people.

Yellow and lemon colors activate motor centers, generate energy for muscles, stimulate the liver, intestines, skin, have laxative and choleretic effects, cause joyful mood. These colors are contraindicated at elevated body temperature, neuralgia, overexcitation, inflammatory processes and visual hallucinations.

Green color eliminates spasms of blood vessels and lowers blood pressure, dilates capillaries, stimulates the pituitary gland, promotes good mood.

The blue color, on the contrary, promotes vasospasm and increases blood pressure, and therefore is contraindicated in hypertension. Has antimicrobial activity. Used for disinfection of premises, treatment of diseases of the ear, throat and nose, gastrointestinal tract. However, it should be remembered that dark blue color with prolonged exposure to a person can cause fatigue and depression.

Indications and contraindications for purple in the clinic are about the same as for blue.

High voltage action

Recently, it has been suggested that children living near high voltage lines transmission lines (power lines) are more at risk of certain types of cancer, particularly leukemia. True, there is no direct evidence from medicine. Nevertheless, the results of epidemiological studies conducted in Sweden, Finland, Denmark and the USA (Poisk, 1995, No. 9) still suggest that high-voltage power lines and various electric power plants can affect the incidence of leukemia and brain tumors in children. Directly under the wires of power lines, even at a minimum voltage of 220 V, the intensity of electromagnetic radiation exceeds the norm of 0.5 kW/m2. Indeed, if you go to the power line clearing, you can see green grass and bright flowers, but there will be no bees on them. They are the most sensitive to electromagnetic waves.

Cell phone: good or bad?

A cell phone is an extremely convenient means of communication that is rapidly conquering "living space". According to experts' forecasts, the number of people (network subscribers) using it in Russia will exceed 1 million, and by the year 2000 - 3 million. Like any relatively new technical device, which is part of our everyday life, it should be evaluated in terms of not only the benefits it brings, but also the safety for the health of users. Today, there is practically no discussion among scientists about whether or not a cell phone affects a person's health. Accumulated knowledge about influence electromagnetic field(EMF) on the human body allow us to say unequivocally that the electromagnetic radiation of a cell phone, like any other source of EMF, affects physiological state and the health of the person in contact with him.

The area of ​​irradiation during the operation of a cell phone is primarily the brain, peripheral receptors of the vestibular, visual and auditory analyzers. When using cell phones with a carrier frequency of 450-900 MHz, the wavelength slightly exceeds the linear dimensions of the human head. In this case, the radiation is absorbed unevenly and so-called hot spots can form, especially in the center of the head. Calculations of the absorbed energy of the electromagnetic field in the human brain show that when using a 0.6 W cell phone with an operating frequency of 900 MHz, the “specific” field energy in the brain is from 120 to 230 μW/cm2 (the standard in Russia for cell phone users is 100 µW/cm2). So, it can be expected that long-term repeated exposure to maximum permissible doses of radiation (especially in the decimeter wavelength range) can lead to significant changes in the bioelectrical activity of various brain structures and disorders of its functions (for example, the state of short-term and long-term memory).

Special experiments by Russian scientists have shown that the human brain not only senses the electromagnetic radiation of a cell phone, but also distinguishes between cellular communication standards. The results of the experiment indicate significant changes in the bioelectrical activity of the human brain. In the majority of testers, both during and after irradiation with electromagnetic waves of a cell phone, the a-band of the bioelectrical activity of the brain increased in the spectra of the electroencephalogram. These changes were especially pronounced immediately after the field was turned off. Other parameters (pulse rate, respiration, electromyogram, tremor, blood pressure) did not respond to exposure to the electromagnetic field of the radiotelephone.

Cell phone radiation is complex modulated. One of the components of the signal of all radiotelephones is low-frequency (for example, in the GSM / DCS-1800 system it is 2 Hz). But it is low (1-15 Hz) frequencies that correspond to the rhythms of the human brain, which exceed other rhythms of the electrical activity of a healthy person in intensity. It has been proven that modulated EMFs can selectively suppress or enhance these biorhythms.

The complex mode of modulation of electromagnetic waves of a cell phone makes us think about allergy sufferers: some of them suffer from exceptionally high susceptibility to electromagnetic fields in certain modulation modes already at a low dose of radiation (1-4 μW/cm2). This should be taken into account when intending to use a cell phone. This warning is also important: people talking on a cell phone inside a car are at particular risk. If the antenna of the device is inside the metal body of the car, then it serves as a resonator and greatly enhances the dose of absorbed radiation.

Apparently, no amount of warnings will be able to stop the rapid growth in the number of cellular subscribers. That is why experts around the world see their task in developing clear recommendations for creating a new generation of equipment operating in the so-called gentle mode of exposure.

Meanwhile, radiotelephones are only a small part of the cellular communication system. Its basis is formed by stationary radio transmitters - the so-called base stations (BC). The more aircraft in the system, the more reliable and stable the connection. In particular, there are already more than 500 aircraft in the Moscow region.

Can such a concentration of emitters pose a danger to the population?

According to the recommendations of the Center for Electromagnetic Safety at the Institute of Biophysics of the Russian Academy of Sciences ( CEO center, doctor of medical sciences, professor Yuri Grigoriev), nothing threatens the residents of the house where the aircraft is installed. Cellular antennas radiate in a narrow sector directed away from the house. Repeated measurements, which were carried out in the course of studying the electromagnetic situation in Moscow and the Moscow region, show that regardless of the transmitter’s affiliation and mode of operation, even on top floor at home in the immediate vicinity of the emitter, the level of the electromagnetic field does not exceed the background. You can get a certain dose if you just climb onto the roof and stand right in the path of the signal. This should not be done.

As for the neighboring houses, the field strength in them is indeed slightly higher than the background one. However, it does not exceed 0.1-0.5 shares of the maximum permissible level (MPL). So the residents of neighboring houses also have nothing to fear. Moreover, Russian electromagnetic safety standards are the most stringent in the world.

For comparison: in the United States, the maximum remote control ranges from 300 to 1000 μW/cm2, depending on the radiation frequency, while in our country it is only 10 μW/cm2.

If the reader wants to know exactly whether the operation of a particular cellular transmitter is allowed, then you should contact the city (republican) center for sanitary and epidemiological surveillance. There you can also see the results of control measurements of the electromagnetic field in your homes.

4.8. Influence of radiation from television towers

Specialists of the Center for Electromagnetic Safety measured the level of electromagnetic radiation in the apartments of houses located near the Ostankino TV tower. In many surveyed premises, an excess of the maximum permissible level (MPL) by one and a half to two times was found.

The document entitled "Sanitary rules and regulations for the protection of the population from electromagnetic fields of radio transmitting objects" establishes for the population the maximum permissible level of EMP in the range of 30-300 MHz as follows: the intensity of the alternating electric field created by radio engineering objects should not exceed 2 V / m for residential buildings of any kind, children's, educational institutions and other premises intended for round-the-clock stay of people. Experts recommend that the level of EMP in living quarters near TV towers, it is necessary to reduce not to the maximum remote control (2 V / m), but to values ​​\u200b\u200bcorresponding to the average background level - less than 0.1 V / m. This "hard" approach is due to the fact that the development of pathological reactions of a particular organism is significantly affected by the amount of absorbed EMR energy, the modulation mode, the duration of its exposure, and such parameters as age and lifestyle.

Therefore, it is very difficult to talk about a safe level. It is different for different people. In addition, an important fact is the possibility of accumulation of the biological effect of EMR under conditions of prolonged exposure (ie, the effect of cumulation). As a result of this process, there is a possibility of such a distant pathology as functional disorders of the nervous system, changes in hormonal status and, as a result, the development of a tumor process. Children and embryos developing in the womb are especially sensitive to the effects of EMR. All this leads to the need to minimize human contact with EMR, and in some cases completely eliminate this additional burden on the human body.

Russia is the first country where studies of the effects of EMR on the nervous system were started. In 1966, in the monograph of Professor Yu.A. Kholodov "The influence of electromagnetic and magnetic fields on the central nervous system" described the direct effect of radiation on the brain, changes in the function of the blood-brain barrier, the effect on neuron membranes, memory, conditioned reflex activity, described the psychophysiological reactions of a person, chronic depression syndrome. Today it can be considered an established fact that even low-intensity EMF exposure causes a tendency to develop stress reactions and memory impairment.

Electromagnetic waves - the inevitable companions of domestic comfort. They permeate the space around us and our bodies: sources of EM radiation warm and light houses, serve for cooking, provide instant communication with any corner of the world. The influence of electromagnetic waves on the human body today is the subject of heated debate. So, for example, in Sweden, "electromagnetic allergy" is considered a disease. Although the World Health Organization still classifies such an organism's reaction as a "possible disease." Among its symptoms are headache, chronic fatigue, memory disorders.

“In my two decades of work, I have not seen any cases of electromagnetic allergy,” says Nina Rubtsova, a doctor, a member of the international expert commission of the WHO Electromagnetic Fields and Human Health program. “But phobias associated with electromagnetic waves have developed in society.” Do we have reasons for them? And how to minimize the likely harm from exposure to radiation?

How does electromagnetic radiation work?

All operating electrical appliances (and electrical wiring) create an electromagnetic field around them, which causes the movement of charged particles: electrons, protons, ions or dipole molecules. The cells of a living organism consist of charged molecules - proteins, phospholipids (molecules of cell membranes), water ions - and also have a weak electromagnetic field. Under the influence of a strong electromagnetic field, molecules with a charge make oscillatory movements. This gives rise to a number of processes, both positive (improvement of cellular metabolism) and negative (for example, destruction of cellular structures).

Everything is ambiguous. In our country, studies of the influence of electromagnetic fields on humans and animals have been conducted for more than 50 years. After hundreds of experiments, Russian scientists have found that most affected are growing tissues, embryos . “It turned out that electromagnetic fields also affect the nervous and muscle tissues, can provoke neurological disorders and insomnia, as well as malfunctions of the gastrointestinal tract - explains Nina Rubtsova. - They are change both heart rate and blood pressure « .

The influence of the electromagnetic field cannot be characterized as unambiguously negative - electromagnetic radiation is used in physiotherapy for the treatment of many diseases: it can accelerate tissue healing and have an anti-inflammatory effect. How exactly the electromagnetic field from ordinary household appliances affects us and how harmful it is to a healthy person is a moot point, therefore it is prudent to shield sources of electromagnetic radiation wherever possible and try to minimize its impact.

So everything household electrical appliances are sources of electromagnetic radiation, and the higher the power, the more aggressive the field . It is most powerful in microwave ovens, refrigerators with a frost-free system, electric stoves and mobile phones. Relatively harmless is considered low-frequency radiation propagating from the mains of the house. The field radiates from the wires even when the circuit is open and no electricity flows through them, but is largely shielded by grounded conductive materials, such as the walls of a house. The magnetic component of electromagnetic fields is more difficult to shield, but it disappears when the appliance is turned off. The exception is electrical appliances with a transformer that are turned off but remain connected to the network (TV, video, etc.). More dangerous is considered high-frequency electromagnetic radiation, the sources of which are radio and television transmitters, as well as radars.

Electromagnetic radiation at home

“In residential premises, it is enough to correctly place Appliances: a bed and sofas, a dining table, that is, those places where we spend a lot of time, should not fall into their field, ”explains Dmitry Davydov, an expert from an independent environmental review company Ecostandard. - When moving away from the source of electrical radiation at a double distance, the field strength decreases by a factor of four. This is the easiest way to minimize exposure to radiation: for example, don't sit too close to the TV."

It is better to place a sleeping place no closer than 10 cm from the wall, especially in houses with reinforced concrete walls. Well, if the wiring has a third ground wire, you can also replace conventional wiring with shielded wiring. It is better if the wires and sockets are closer to the floor, and not at the level of the human belt, as is often the case. Electric heated floors generate a field of up to one meter above the surface, so it is best not to place them under the bed or in the nursery. However, this disadvantage can be compensated for with the help of shielding paints, wallpaper and fabric materials.

induction cookers generate strong magnetic fields, preferably ceramic-metal hobs. The most modern models of microwave ovens are relatively safe: now most manufacturers pay Special attention their high tightness. You can check it if you carry a sheet of aluminum foil in front of the door of a working microwave oven: the absence of crackling and sparks will confirm that everything is in order.

Electromagnetic radiation at work

For those who work a lot at the computer, there is a simple rule: there should be a distance of about a meter between the face and the screen. And of course, plasma or LCD screens are safer than cathode ray tubes. Radio and mobile phones are another source of radiation that we can't avoid. These are transmitter-receiver devices that we hold near our ears and allow the radiation to act directly on the brain. “The question of the degree of harmfulness of mobile phones is being discussed,” Ecostandard specialist Alexander Mikheev comments on the problem. – The power of electromagnetic radiation of a mobile phone is a variable value. It depends on the state of the communication channel " mobile phone – base station". The higher the signal level of the station in the place of reception, the lower the radiation power of the mobile phone. As a precautionary measure, you can suggest the following: carry the phone in a bag or briefcase, not on the belt or on the chest, use a handsfree headset, especially when long calls are needed, choose models of phones with the lowest radiation power, especially for children. Children under the age of 12 should not use a mobile phone at all.”

Electromagnetic radiation outdoors

High voltage power lines (HPL) are hazardous to health - it is forbidden to build housing under them, but you can pass under them. There are many hypotheses that justify harmful effect Power lines on our body, - explains Alexander Mikheev. “According to one of them, power lines ionize dust particles flying nearby, which, getting into the lungs, transfer their charges to cells, disrupting their functions.”

Many of us are frightened by the proximity of cellular antennas, which are sources of ultra-high frequency electromagnetic waves, with power lines. "According to existing rules, antennas of transmitting radio engineering objects are recommended to be placed on separate supports, but placement on the roofs of buildings, including residential ones, is also allowed, - Alexander Mikheev continues. - The main radiation energy (more than 90%) is concentrated in a rather narrow "beam", and it is always directed away from buildings and above adjacent buildings. This is necessary condition for the normal functioning of the communication system.

As Ecostandard told us, although in theory these antennas can have a harmful effect on health, in practice there are no grounds for alarm: studies of the electromagnetic environment in the area where the antennas were located were carried out by specialists from different countries, including Sweden, Hungary and Russia. In 91% of cases, the recorded levels of the electromagnetic field were about 50 times less than the permissible level.

Electromagnetic waves that heal

A whole branch of medicine physiotherapy– successfully uses electromagnetic radiation for treatment various diseases. The PhD, head of the department of physiotherapy and rehabilitation treatment of the Research Institute of Pediatrics and Pediatric Surgery of Rosmedtekhnologii, physiotherapist Lev Ilyin tells how this happens.

“Let me remind you that many large molecules of our body are polar, therefore, as a result of exposure to a non-permanent magnetic field, metabolism, enzymatic processes are activated, and cellular metabolism improves. This allows the use of magnetotherapy for edema, treatment of joints and for resorption of hemorrhages. The action of low-power direct current impulses on brain structures contributes to a deeper and restful sleep. Such electrosleep is an important part of the treatment of hypertension, neurasthenia, sleepwalking and some vascular diseases. In acute inflammatory processes, the well-known UHF is used - a device that generates an electromagnetic field of ultrahigh frequency with a short wavelength. The tissues of our body absorb these waves and convert them into thermal energy. As a result, the movement of blood and lymph is accelerated, the tissues are freed from fluid stagnation (common in inflammation), and the functions of the connective tissue are activated. The apparatus for UHF therapy also allows you to relieve spasms of the smooth muscles of the stomach, intestines, gallbladder, accelerates recovery nervous tissue, reduces the sensitivity of terminal nerve receptors, that is, it contributes to pain relief. It also reduces the tone of capillaries and arterioles, lowers blood pressure and reduces the heart rate.

Mechanism of EMR influence

The human body, like any organism on Earth, has its own electromagnetic field, thanks to which all systems, organs and cells of the body work harmoniously. Human electromagnetic radiation is also called a biofield. The visual representation of the biofield, which some people see, and which can be built by a computer with the help of special devices, is also called an aura.

This field is the main protective shell of our body from the influence of external electromagnetic fields. When it is destroyed, the organs and systems of our body become easy prey for any disease-causing factors.

If other sources of radiation, much more powerful than the radiation of our body, act on our natural electromagnetic field, then it is distorted or even begins to collapse. And chaos begins in the body. This leads to disruption of the work of various organs and systems - diseases.

That is, for any person it is obvious that, for example, a buzzing transformer box or a powerful electric generator are dangerous, because they create a strong electromagnetic field around them. Safety time and distance standards have been calculated for workers when they are near such devices. But here's what is NOT obvious to most people:

The same effect of destruction of the biofield occurs when exposed to weak electromagnetic radiation, if the body is under their influence regularly and for long periods of time.

That is, the sources of danger are the most common household appliances that surround us every day. Things we can't imagine our life without: Appliances, computers, laptops, mobile phones, transport and other attributes of modern civilization.

In addition, a large crowd of people, the mood of a person and his attitude towards us, geopathic zones on the planet, have a significant impact on us. magnetic storms etc. (for more details see page ).

Among scientists, there are still disputes about the dangers of electromagnetic radiation. Some say that it is dangerous, others, on the contrary, do not see any harm. I would like to clarify.

The most dangerous is not the electromagnetic waves themselves, without which no device could really work, but their information component, which cannot be detected by conventional oscilloscopes.

It has been experimentally established that electromagnetic radiations have a torsion (information) component. According to the studies of specialists from France, Russia, Ukraine and Switzerland, it is torsion fields, and not electromagnetic ones, that are the main factor negative impact on human health. Since it is the torsion field that transmits to a person all that negative information, from which headaches, irritations, insomnia, etc. begin.

How strong is the impact of the technology around us? We offer several videos for viewing:

How dangerous radiation surrounds us? Visual demonstration:

Of course, these are far from all the dangerous items that we use on a daily basis. More information about radiation sources can be found on the page:

Effect of electromagnetic radiation on human health

Weak electromagnetic fields (EMFs) of high frequency with a power of hundredths and even thousandths of a watt are dangerous for a person because the intensity of such fields coincides with the intensity of the radiation of the human body during the normal functioning of all systems and organs in his body. As a result of this interaction, a person's own field is distorted, which contributes to the development of various diseases, especially in the most weakened parts of the body.

The most dangerous property of such effects is that they accumulate over time in the body. As they say: "a drop of water wears away a stone." People who, by occupation, use a lot of various equipment- computers, telephones - a decrease in immunity, frequent stress, a decrease in sexual activity, increased fatigue were found.

And if we take into account the development of wireless technologies and the miniaturization of gadgets that allow us not to part with them around the clock... Today, almost every resident of the metropolis, who is somehow exposed to mobile and Wi-Fi networks, power lines, electric transport, etc., is at risk around the clock. .

The problem is that the danger is invisible and intangible, and begins to manifest itself only in the form of various diseases. At the same time, the cause of these diseases remains outside the field of view of medicine. With rare exceptions. And while you are healing the symptoms with the achievements of modern medicine, our invisible enemy stubbornly continues to undermine your health.

The most affected by electromagnetic fields are the circulatory system, brain, eyes, immune and reproductive systems. Someone will say: “So what? Surely this impact is not so strong - otherwise international organizations would have sounded the alarm long ago.

Facts:

Did you know that within 15 minutes after starting work on the computer, 9-10 summer child changes in the blood and urine almost coincide with changes in the blood of a person with cancer? Similar changes appear in a 16-year-old teenager after half an hour, in an adult - after 2 hours of work at the monitor.

(we are talking about cathode ray monitors, which are gradually disappearing from everyday use, but are still found)

US researchers found:

• in most women who worked on computers during pregnancy, the fetus developed abnormally, and the probability of miscarriage approached 80%;
• brain cancer in electricians develops 13 times more often than in workers of other professions;

Effect of electromagnetic radiation on the nervous system:

The level of electromagnetic radiation, even without causing thermal effects, can affect the most important functional systems of the body. Most experts consider the nervous system to be the most vulnerable of them. The mechanism of action is very simple - it has been established that electromagnetic fields disrupt the permeability of cell membranes for calcium ions. As a result, the nervous system begins to malfunction. In addition, an alternating electromagnetic field induces weak currents in electrolytes, which are the liquid constituents of tissues. The range of deviations caused by these processes is very wide - during the experiments, changes in the EEG of the brain, a slowdown in reaction, memory impairment, depressive manifestations, etc. were recorded.

Effect of EMR on the immune system:

The immune system is also affected. Experimental studies in this direction have shown that in animals irradiated with EMF, the nature of the infectious process changes - the course of the infectious process is aggravated. There is reason to believe that under the influence of EMR, the processes of immunogenesis are disturbed, more often in the direction of their suppression. This process is associated with the emergence of autoimmunity. In accordance with this concept, the basis of all autoimmune conditions is primarily immunodeficiency in the thymus-dependent cell population of lymphocytes. The effect of high-intensity EMF on the body's immune system is manifested in a depressing effect on the T-system of cellular immunity.

Effect of EMR on the endocrine system:

The endocrine system is also a target for EMR. Studies have shown that under the action of EMF, as a rule, stimulation of the pituitary-adrenal system occurred, which was accompanied by an increase in the content of adrenaline in the blood, activation of blood coagulation processes. It was recognized that one of the systems that early and naturally involves the body's response to the impact various factors external environment is the hypothalamus-pituitary-adrenal cortex system.

Effect of electromagnetic radiation on the cardiovascular system:

You can also note the violations of the cardiovascular system. It manifests itself in the form of lability of the pulse and blood pressure. Phase changes in the composition of peripheral blood are noted.

The influence of electromagnetic radiation on the reproductive system:

1. There is a suppression of spermakinesis, an increase in the birth rate of girls, an increase in the number of congenital malformations and deformities. The ovaries are more sensitive to the influence of electromagnetic radiation.
2. The female genital area is more susceptible to the effects of electromagnetic fields generated by computers and other office and household appliances than the male.
3. Vessels of the head, thyroid gland, liver, genital area are critical areas of influence. These are just the main and most obvious consequences EMI exposure. A picture of the real impact on everyone specific person very individual. But to one degree or another, these systems are affected by all users of household appliances at different times.

Effect of electromagnetic radiation on pregnant women and children:

The children's organism has some peculiarities in comparison with an adult, for example, it has a large ratio of the length of the head and the body, and a greater conductivity of the medulla.

Due to the smaller size and volume of the head of a child, the specific absorbed power is greater than that of an adult, and the radiation penetrates deeper into those parts of the brain that, as a rule, are not irradiated in adults. With the growth of the head and the thickening of the bones of the skull, the content of water and ions decreases, and hence the conductivity.

It has been proven that growing and developing tissues are most susceptible to the adverse effects of the electromagnetic field, and active human growth occurs from the moment of conception to about 16 years.

Pregnant women also fall into this risk group, since EMF is biologically active in relation to embryos. When a pregnant woman talks on a cell phone, virtually her entire body is exposed to EMF, including the developing fetus.

The sensitivity of the embryo to damaging factors is much higher than the sensitivity of the maternal organism. It has been established that intrauterine damage to the fetus by EMF can occur at any stage of its development: during fertilization, crushing, implantation, organogenesis. However, the periods of maximum EMF sensitivity are early stages embryo development - implantation and early organogenesis.

Facts:

In the Neurodiagnostic Research Institute in Spain in 2001, they found that in 11-13-year-old children who talked on a cell phone for two minutes, the change in the bioelectrical activity of the brain persisted for another two hours after they hung up.

The University of Bristol in the UK ended a study last year showing a significant increase in reaction time in 10-11 year old children who used a GSM mobile phone. Similar results were obtained by the Finns at the University of Turku, who observed a group of children 10-14 years old.

In the USSR, until the 1990s, a large number of studies of the biological effect of EMF on the developing animal organism were carried out.

It has been established that even low EMF intensities affect the embryonic development of offspring. The offspring of irradiated animals are less viable, developmental anomalies, deformities, lag in weight, dysfunctions of the higher parts of the central nervous system (slow production and reduced ability to maintain defensive and motor-food conditioned reflexes), and a shift in the pace of postnatal development are observed.

EMF-irradiated adult animals are characterized by a decrease in the number of offspring, changes in the genital organs of females, disturbances in the development of the fetus, a decrease in the percentage of interbreeding, and statistically more frequently observed cases of stillbirth.

A study of the effect of EMF on the offspring of rats exposed to electromagnetic effects in parameters similar to what a human embryo receives when its mother talks on a cell phone showed that, compared with the control, the embryonic mortality of the offspring is statistically significantly increased, the mass of the thymus gland is reduced, and the number of developmental anomalies is increased internal organs, for the first 4 weeks of the postnatal period, the mortality of the offspring of rats of all experimental groups was 2.5-3 times higher than in the control, and body weight was lower. The development of rat pups also went worse: the formation of sensory-motor reflexes, the timing of the cutting of incisors lagged behind, in female rat pups formation was disturbed.
